Description

Earthquake magnitude from Sbeinati et al. (2005).

Detailed investigation by Darawcheh et al. (2000) and Elias et al. (2007). Summary by Salamon et al. (2007, 2011). Some studies (Ambraseys and Jackson, 1998; Ambraseys et al., 1994) place the earthquake in, around, or offshore Lebanon. Darawcheh et al. (2000) suggest the Roum Fault. Most recent studies by Daeron et al. (2004) and Elias et al. (2007) suggest an earthquake on the Beirut (Mount Lebanon) thrust (Salamon et al., 2011).

Tsunami in Lebanon, between Tyre and Tripoli.(Guidoboni et al., 1994; Ozansoy, 1999; Sbeinati et al., 2005; Soysal et al., 1981; Yolsal et al., 2007).

Ambraseys (1962) mentions a tsunami on the Syrian coast. Ambraseys et al. (1994) mention a "Seismic sea wave on the coast of Phoenice". Ambraseys (2009), states that “Along the coast of Phoenice the sea receded for many hours stranding sailing boats in the shallows. Then the sea came back, throwing ships on land, causing great havoc before returning to its original level.”. Amiran et al. (1994): "Tsunami at Lebanese coast. May have affected Caesarea." Guidoboni et al. (1994): "... the sea retreated for a mile and many ships were destroyed.” A recent study of Darawcheh et al. (2000) restricts the tsunami between Tyre and Tripoli.

Following historical sources, Guidoboni et al. (1994) mention that cities along the Lebanese and Syrian coasts, including Beirut, were destroyed.

In Botrys Mt. Lithoprosopon broke off and fell in to the sea, and formed a new harbour; the sea retreated for a mile and then was restored to its original bed. Many ships were destroyed (Guidoboni et al., 1994; Ozansoy, 1999; Altinok et al. (2011).). According to Soloviev et al. (2000) the sea retreat was about 1 km.
